Our UK guidance uses the terminology UK buyers actually use: intruder alarms, CCTV monitoring, alarm receiving centres, keyholder response and remote monitoring. Compliance standards, response policies and operational expectations differ from the US — our UK-focused pages reflect that.
Placeholders are used where future references to UK standards, accreditations or compliance frameworks will be added — we don't publish unverified claims.
Frequently asked questions
What is a commercial intruder alarm in the UK?
A commercial intruder alarm in the UK typically combines internal detectors (door contacts, PIRs, dual-tech) and external detection where appropriate, signalled to an alarm receiving centre for verified response.
What is an alarm receiving centre?
An alarm receiving centre (ARC) is a monitoring facility that receives alarm signals from commercial sites, verifies events and follows the agreed escalation pathway — typically keyholder, mobile response or police.
What is keyholder response?
Keyholder response is the service where a third-party security company attends a site following a confirmed alarm, replacing the need for a member of staff to respond out of hours.
Are compliance standards different in the UK?
Yes — UK commercial alarm systems and monitoring are subject to UK-specific industry standards and police response policies. Specialist installers and ARCs can advise on the relevant requirements for your site.
